"Influenza has now been reported in 476 counties, including 94 with community-wide epidemics. Many schools have been temporarily closed an d industrial absenteeism has increased, but there is little evidence of serious disruption of community function as seen in some other countries. Seven deaths have been reported among mental defectives at a large institution. Susceptibility to bacterial complications appears to increase the risk from influenza in these persons as evidenced by this and other similar reports. Excess mortality for the entire Untied States continues to rise, with the greatest relative increase in the Middle Atlantic Division (New York, New Jersey, Pennsylvania). The total excess for the week ending October 19 is approximately 300 deaths. Although these may not necessarily be all related to influenza, there is a striking association of reported epidemics, industrial absenteeism, and excess influenza and pneumonia mortality. A case summary is recorded of an influenza-associated death in an 18-year -old college student with staphylococcal pneumonia as the cause of death. These case summaries represent only a small fraction of the deaths associated with influenza, and should not be considered representative of the majority of deaths. Most of the deaths reported to the Influenza Surveillance United have been in the young adult group, but there is no reason to believe that this represents the nationwide age distribution. A total of 22,765,436 ml of Asian strain vaccine has been released through October 16. This includes 7,136,515 ml released since October 7. The average duration of 25 influenza epidemics in the U. S. A. since 1915 has been 13 weeks, with variations of 6 to 31 weeks. Duration was measured by excess influenza-pneumonia mortality rates as explained in Appendix A." - p. [2]

Tropical cities such as Singapore do not have well-defined influenza seasons but have not been spared from influenza pandemics. The 1918 epidemic in Singapore, which was then already a major global trading hub, occurred in 2 waves, June-July, and Oct...
